Abstract
The patient was a 79-year-old man who had an ileocecal resection and a low anterior resection for multiple cancers of the cecum and rectosigmoid in October 2009. The histopathological diagnoses were mucinous adenocarcinoma of the rectosigmoid and a well-differentiated tubular adenocarcinoma of the cecum. Adjuvant chemotherapy involving oral UFT + LV was given. After 10 months, computed tomography (CT) showed cystic lesions in the right lower abdomen, involving the ileum and colon anastomosis. Myxoma or metastatic tumors were considered, and a partial resection of the colon including the anastomosis was done in February 2011. The lesions were not continuous with the lumen of the colon and were diagnosed as metastatic lesions of mucinous adenocarcinoma on histopathology. The disseminated metastases at the drainage tube site was likely related to the previous surgery.
